Fire alarm panel supply

Good morning.

I have a question that may sound silly so excuse my ignorance in advance

I have a Fire Alarm Panel

This is going to be fed through FP200.

However the installation of the FP200 would need an RCD because it is chased within a stud wall less than 50mm from the surface.

Can I omit the RCD on the grounds that it is a critical system for the safety of people?

Is there anything like that in BS7671?

It seems really counter intuitive to use an RCD on a Fire Alarm Panel...

Thanks

This sounds like a commercial job to me - so why do you specifically thing an RCD is required for the circuit ?

I am no expert on fire alarms, but a large dwelling (at least one floor of 200 m²) of three storeys requires Grade A Category LD2. As I understand it, that means a panel. So either we have an RCD, or surface mounted (which won't do in a grand home, save perhaps below stairs), or screened/metal conduit, etc. Not an ideal situation!
